NON-REFILLABLE BOTTLE.

Specification of Letters Patient.

Application led lFebruary 21, 1910. Serial No. 545,052.

To all whom 'it may concern:

Be it known that I, WILLIAM WHITE CLARK, a citizen of the United States,and a resident of Covington, in the county of Newton and State ofGeorgia, have invented a new and Improved Non-Refillable Bottle,

of which the following is a full, clear, andL a i f said passage isfurther extended downward exact description.

This invention relates to a class of liquidi packages designed toprevent the refillingE of the vessel after the original contents havetapered opening is formed that crosses the been decanted.

The purpose of this improvement is to provide novel features ofconstruct-ion fory a device of the character indicated, which willpositively seal the bottle against applied pressure in case an attemptis made to refill the same by use of a force pump. -Ihe inventionconsistsin the novel construction and combination` of parts, as ishereinafter described and defined in the appended claims.

Reference is t0 be had to the accompanying drawings forming a part ofthis specification, in which similar characters of ref-` erence indicatecorresponding parts in all the views. v

Figure 1l is a longitudinal sectional view of the improvednon-refillable bottle, showing the same filled with liquid; Fig. 2 is alongitudinal sectional view showing the bottle emptied, and partsadjusted to seal the inlet to the bottle against the introductionofliquid; and Fig. 3 is a side view of a sealing valve forming a detail ofthe invention. t

The body 5 of thebottle is preferably given cylindrical form, molded orblown from glass, the interior wall thereof being a true bore open atthe lower end, wherein is -closely fitted a preferably flat bottom 6also formed of glass having a true peripheral wall a; from whichdownwardly extends a tapered flange'a, as shown in Fig. 1.

The upper portion of the body 5 is contracted and thickened as at 5a,forming a thick top ,wall from which thej neck 7 0f the bottleintegrally projects, the lower p0rtion 7 a of said'neck being a solidextension of the body portiona. Above the neck portion 721.| the neck 7is centrally bored as at b, said bore having sufficient dimensions toprovide a liquid receivin compartment, that will .also serve as adischarge passage for the outflow of liquid contained in the body 5, aswill be hereinafter fully explained.

From the bottom wall of lthe receiving Patented Dec. 12, 1911.

compartment b adjacent to the side wall of f i said compartment, apassage c, of le'ss diameter than the bore b, is downwardly extendedinthe neck portion 7a and body por tion 5a to a point c, where saidpassage is i laterally extended to a point c2, from wzliich as at c3 vto04, where it intersects the bore of the body 5 as shown in the drawings.

Transversely in the neck portion 7a a passage c, said opening beingclosed by a tapering plug valve 8, that is provided with a thumb piece8"" on its larger end, for its manual rotation. In the plug valve body 8a transverse passage d is formed, that is tight within the cylindricalbore of the.

body 5, and transversely therein a slot e is formed, said slot having aninclined bottom wall e and a horizontal top wall,` thus rendering saidslot tapering or wider at one end than the other, as is clearlyshown inFigs. 1 and 3. A cylindrical locking rod or bar 10, is loosely fittedwithin the slot e, and at its ends has Contact with'the bore of the body5 when at rest or lying on the inclined bottom wall e.

The bottle is designed to receive and hold liquids of any density. Whenthebottle is in course of construction, the disk valve 9 is positionedin the bottle at the place ascribed to it in Fig. 1. The compartment 11below the disk valve 9 is filled with compressed air after thecompartmentflQ above the disk valve 9 'has been filled with compressedair. This precaution is taken so that the disk valve 9 will not slideupk in the bottle when the compartment 11 is being filled withcompressed air.v The 'bottom 6 is then inserted within the lower end ofthe bottle body 5. The air pressure in the compartment 11 is easilysufcient to lift the combined weight of the disk valve 9 and a volume ofthe heaviest known liquid substance, which is'equal l'in size to thevolume of the compartment 12. The air pressure in the compartment 12 ismade sufficient to counterbalance the force exerted in the compartment11. t As before mentioned, the

the bottom to the lower edge of the bottle body, said edge portion g issimilarly tapered.

When the bottle is empty and is to be filled with liquid, the disk valve9 is positioned about an inch from the bottom of the bottle (as shown inFig. 1) and by suitable means the bottom 6 is secured within the loweredge of the body 5, preferably by fusing the lower edge of the flange 6aand tapered edge g together. The disk valve 9 is held in this positior.by the counter-balancing pressures in the compartments'll and 12 of thebottle. To fill the bottle with liquid, the plug valve 8 is closed, andthe bore in the neck 7 is filled with some of the liquid that is to beplaced in the bottle. open upper end of the neck 7 by pressing the palmof one hand forcibly down upon the mouth of the bore b, thus renderingsaid bore air-tight, and then turns the valve 8, to cause the passage din said valve to register with the passage c and the continuationthereof through the body of the bottle. This is done so that thecompressed air will not escape from the body of the bottle faster thanthe rate at which the liquid flows into the bottle, for in case theescape of such air is at a rate faster than the inward iiow of theliquid, the disk valve 9 will rise and close the bottle before thelatter is filled. The liquid in the bore Z) then descends through thepassage c, the passage Z in the valve 8 and the continuation of thepassage 0 into the body of the bottle above the disk valve 9. As thistakes place, the compressed air in the body of the bottle ascends by thesame course and takes the place of the liquid as the latter leaves thebore b. The operator then removes his hand from the mouth of the bore o,and the operation above described is then repeated until the bottle isfilled with the liquid.

Throughout the operation, although the compressed air is graduallydiminished, its pressure remains the same, since the space which the airoccupies is diminished in proportion by the inflowing liquid. The airbelow the disk valve 9 is compressed air, not simply compressed by theweight of the disk valve 9 and of the liquid above it, and the aircontained in the body of the bottle above the disk valve 9 is alsocompressed air, to offset the pressure below the said valve.

It will be seen that as the liquid is decanted through the plug valveand bore Z) in the neck 7, the disk valve will rise, and when thecontents of the bottle are completely removed the disk valve 9 willremain pressed by the air below it, so as to seal the lower end c4 ofthe passage 0 (as The operator now closes theA shown in full lines inFig. 2) and thus prevent the re-filling of the bottle. And it also willbe apparent that the offset bends in the passage o will prevent theintroduction of a wire or the like for holding the disk valve 9 open, soas t-o refill the bottle. Vhen the bottle is filled, the ope-n upper endof the bore will be provided with a suitable closure, which willcomplete the filled bottle as an original liquid package.

As long as the disk valve 9 ascends, the rod 10 rests on the inclinedbottom wall e of the slot e, but the moment the disk valve starts todescend (when in any posit-ion in the bottle body), the upper wall ofthe slot e bears on the rod 10 and the latter is wedged within thebottle body, since the upper wall of the slot e' is horizontal and thebody of the round rod 10 is too long for said rod to assume a horizontalposition within the bottle body, or in other words, the pressure willtend to cause the rod 10 to lie horizontally, but as said rod is toolong for it to so lie, it will wedge itself in the bottle body.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. rlhe combination with a vessel, of a disk valve in the vessel andprovided with a horizontal passage extending through it, and a memberloosely held in the passage of the valve and permitting the free ascentof the' valve but preventing its descent.

2. In a device of the character described, the combination with thecylindrical Abody having a true bore, of a disk valve slidably fitted inthe said bore, said valve having a transverse horizontal passagetherethrough and a freely movable locking rod in th'e said passage. v

3. The combination with a'vesse'l, of( a disk valve movable in thevesselan'dyprq vided with a transverse passage havingone of its wallsinclined, and an elongated member freely movable in the passage. 4

4. The combination 'with a vesselof a disk valve movable in the Vessela'nd--provided with a horizontal passage having a horizontal top walland an inclined bottom wall, and a rod in the 'passage of the valve andof a length greater than the diameter of said valve.

In' testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
